Former GOP senator Ayotte joins Caterpillar board of directors

Former U.S. Sen. Kelly Ayotte (R-N.H.) is the newest addition to the Caterpillar board of directors.

"During her career as a public servant, Kelly has distinguished herself and has been widely recognized for her independence and her ability to work collaboratively across political lines to serve the best interests of her constituents and her country. I look forward to working with her on the board," said Caterpillar Chairman Dave Calhoun.

Ayotte served on the Commerce Committee as a senator. She also worked to extend the Export-Import Bank, which provides subsidies to companies.

The 49-year-old lost her re-election fight to Democratic New Hampshire Gov. Maggie Hassan last year.
